All you have to do is roll a few long sheets of adhesive contact paper onto the wall where you hang or lean your bike. It will shield your paint from any scuffs and scratches from the bike, and you can easily peel it off when you move. Most tire marks would probably come off with some elbow grease and a Magic Eraser, but this trick saves you the work, and can help prevent any permanent damage if you scrape the wall badly.
